Genetic mapping of schizophrenia a big step forward

Scientists from more than 30 countries have collaborated on a study that maps the genetic markers for schizophrenia. They found more than 100 areas in human DNA that seem to contribute to the disorder, 83 of which had not been known before. Their research - Biological insights from 108 schizophrenia-associated genetic loci - has been published in the journal Nature. Professor Jo Knight was one of the researchers. She's a behavioural neurobiologist at the Centre for Addiction and Mental Health (CAMH) in Toronto. You can read her comments in this CBC article. You can also watch some short videos where Dr. Kwame McKenzie, psychiatrist at CAMH, talks about what we know now about the causes of psychosis.
